The palmaris longus tendon was reported absent in North American Caucasians 24.4% of the time in one or both arms, by Thompson in 1921. Some studies have described its absence as being more frequent in females, and its bilateral absence more frequent than its unilateral absence. This study randomly evaluated 200 Caucasian patients (100 of each sex), seen in an office or hospital setting, for the presence of the palmaris longus tendon. It was absent in one extremity in 3% of the patients. Two and one-half percent of the patients had bilateral absence for a 5.5% total overall absence. This study demonstrated that absence of the palmaris longus tendon in North American Caucasians was considerably lower than reported by Thompson in his report in 1921.
1921年汤普森报告称，北美白种人中，一侧或双侧掌长肌腱缺失的情况占24.4%。一些研究表明，掌长肌腱缺失在女性中更为常见，双侧缺失比单侧缺失更为常见。本研究随机评估了在诊所或医院就诊的200名白种人患者（男女各100名）掌长肌腱的情况。3%的患者一侧肢体掌长肌腱缺失。2.5%的患者双侧掌长肌腱缺失，总体缺失率为5.5%。本研究表明，北美白种人中掌长肌腱缺失的比例远低于汤普森1921年报告中的比例。
